Ata marie,

Hmm its a tricky one owen, there is no date_created field on the like on 
the biblio table. So you cant do a date range search, but certainly, as 
the biblionumber increments upwards all the time, you could grab the 
last 10 biblionumbers, those would be the last 10 biblios added.

Something like
SELECT title,author,biblionumber FROM biblio ORDER BY biblionumber DESC 
LIMIT 10;
